Gas velocity as well as gas fl ow angle to the probe can be cal-culated from these values. Tempe-rature is recorded by an integrated PT100 sensor within the probe head.A cut-off valve prevents a back fl ow to the dust collector before and af-ter sampling. The extracted partial volume fl ow is measured using fl ow measurement with restriction.Simple connection of fi lter head probe and automatic unit by screw lock gasket mechanismSpecial bracketTemperature sensorHC dust collectorLC dust collectorAutomatic unitFilter head probe GS5SICK MAIHAK GmbH | GermanyNimburger Str. 11 | 79276 Reute | www.sick.comPhone +49 7641 469-0 | Fax +49 7641 469-1149 | info.pa@sick.de 8007741/2009-06 · DIV03/KE · Printed in Germany (2009-08) · Subject to change without prior noticeTechnical data SHC500 GRAVIMATMeasuring parametersMeasuring components Dust concentration with gravimetrical comparison measurementMeasuring ranges 0.1 ... 200 mg/m• 3 with dust collector LC50 ... 50,000 g/m• 3 with dust collector HCAccuracy ± 1 % of maximum throughputMeasuring conditionsMedium temperature Standard: 0 ... 250 °C (32 … 480 °F) • With air cooling: 0 ... 400 °C (32 … 700 °F) • Special version: 0 ... 600 °C (32 … 1,110 °F) • Internal duct pressure –70 ... +70 hPa (–1.0 … 1.0 psi)Gas velocity 2 ... 48 m/s (6.6 … 157.5 ft/sec)Ambient conditionsUmgebungstemperatur –10 ... +50 °C InterfacesInterface RS232: 9600, N, 8, 1General informationSystem components Automatic unit SHC-AE501/502• Filter head probe GS5• Dust collector LC oder• Dust collector HC• Operation Via LC-Display and Function key pad; Version SHC502 with operational software• ApprovalsCompliances EN 13284-1• US-EPA Method 17•
